Convert Images Online

Convert images between HEIC, JPG, PNG, and WebP

Different devices and platforms speak different image formats. iPhones save photos as HEIC, the web prefers WebP, and almost everything accepts JPG. This converter bridges them all in your browser — decode HEIC, swap between PNG, JPG, and WebP, and process a whole batch at once.

How the conversion works

For HEIC and HEIF files, a bundled decoder unpacks the HEVC-compressed image into a bitmap first. Every image — HEIC or otherwise — is then drawn to an HTML canvas and re-encoded into your target format and quality. Because the whole pipeline runs on-device, even Apple's proprietary HEIC photos convert without any server, plugin, or app install.

A format decision tree

Format choice is not about which is "best" — each was designed for a different job. Walk these questions in order and the answer falls out:

1. Does the image need transparency? If yes, JPG is out of the running entirely; choose PNG for guaranteed support everywhere, or WebP if every place the file will land is reasonably modern.
2. Is it a photograph, or flat graphics and text? Photographs — continuous tone, lots of subtle gradients — compress beautifully with the lossy codecs (JPG, WebP). Screenshots, logos, charts, and line art have hard edges and large flat regions that lossy compression smears into halos, so they belong in lossless PNG (or lossless WebP).
3. Where will it be opened? If the answer includes an old email client, a legacy app, or a print shop, JPG is the safest currency. If it is a website or app you control, WebP buys you roughly 25–35% smaller files at the same visible quality.
4. Do you need to edit it again later?Then convert to a lossless format for the working copy, so repeated saves don't accumulate generation loss, and only export to lossy JPG/WebP at the very end.

Worked through: an iPhone HEIC of a landscape that you want to email becomes JPG (photo, broad compatibility, no transparency). A cut-out product PNG for your store becomes WebP (transparency needed, modern target, smaller file). A scanned contract becomes PNG (sharp text edges must stay crisp).

Private and offline-capable

Because both the HEIC decoder and the canvas encoder ship to your browser, a batch of phone photos converts at the speed of your processor with the network unplugged — useful on a plane or a locked-down work laptop, and a guarantee that proprietary HEIC files are never copied to anyone's cloud.
